Modeling a Moxon-Yagi Dual Band VHF/UHF Satellite Antenna

Adjust the indicated gaps to minimize the VSWR.

This model is self-resonant (50 Ohm) in the analyzed frequency range, so it does not need a matching network.

I'm curious about this one.

The rear of the Moxon is supposed to be a reflector.  Why is there a new reflector inside the rectangle?

The directors length and spacing differ wildly from the dipole, how were these calculated for construction?

Hello!

This is a dual band antenna. The "Moxon" part of the antenna works on VHF, while the "Yagi" part of the antenna works on UHF. 

The element inside the Moxon rectangle is the reflector of the Yagi antenna, since the rectangle cannot function as a reflector in UHF. The lengths of and spacing between the directors of the Yagi correspond to UHF frequencies.

Best regards
